"Regarding the mask issue:"
This may be the best how to wear a mask advice I have ever seen. The claustrophobia issue is very real and not rare. It will prevent something a bit over 10% of the population from wearing a mask and can not be cured by any simple methods. The very mild impediment to breathing that everyone feels is easy to overcome as long as the person does not suffer from claustrophobia.
If you do get a breath that contains fog you will feel it in your throat and have an urge to cough that can not be suppressed. It will be a deep cough that is likely the hardest you have ever coughed in your life unless you have happened to work around chlorine. I would rate a chlorine cough as more than ten times worse. Neither a chlorine nor an oxalic acid fog cough is going to kill you unless it happens to trigger something like a heart attack. In that case you were going to die anyhow, just not for a few more hours. But the cough can make you feel pretty miserable for a few minutes in the case of oxalic fog or a couple of hours in the case of chlorine.
The beard issue is smaller than someone trained in how to use a mask properly might think. The oxalic fog particles are so huge that a beard is a very decent filter, so even thou it will cause leaks the particles are filtered well enough that you do not feel a thing in your throat based on my personal experience. Even a garden variety N95 mask with the rather weak elastic straps and my full beard is enough to stop any throat irritation when purposely standing in a fog cloud and breathing. As a chemist I remind everyone that all chemicals are poisons regardless if produced in the lab by humans or produced by mom nature. I encourage everyone to use oxalic with reasonable care to avoid exposure. However, to put things in perspective, I consider use of formic acid quite a big more dangerous than oxalic acid. In fact, I consider formic acid to be the most dangerous chemical beekeepers use in their bee program. And, the danger of a smashed disk from all the awkward lifting we do is overall an even bigger hazard if we want to measure risk by lost man hours of work.
